How can I compare a string to multiple correct values in Bash?

I have the following piece of Bash script:

function get_cms {
    echo "input cms name"
    read cms
    cms=${cms,,}
    if [ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]; then
        get_cms
    fi
}

But no matter what I input (correct and incorrect values), it never calls the function again, because I only want to allow 1 of those 3 inputs.

I have tried it with ||, with [ var != value ] or [ var != value1 ] or [ var != value1 ], but nothing works.

Can someone point me in the right direction?

Solution

  • Instead of saying:

    if [ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]; then

    say:

    if [[ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]]; then

    You might also want to refer to Conditional Constructs.
